I was looking through the Febuary Super Chevy Mag, and came across an ad for a new manifold from Edelbrock. They have a Dual quad RPM Air gap. The ad says that it's available for the SBC. I wonder if they will make it for the the BBC in the future. I looked on their web site and didn't see it there.

If you have an interest in a big block dual quad air gap, then let Edelbrock know. They will make them if there is marketplace demand.
